‘Billions’ Season 7 Episode 9 Photos, Cast, and “Game Theory Optional” Plot

Showtime’s Billions season seven episode nine will, finally, find Mike Prince’s enemies making their big move(s). Episode eight felt weirdly out of place and like filler, so hopefully episode nine will more than make up for “The Owl.”

Episode nine, “Game Theory Optional,” will air on Paramount+ with Showtime on Friday, October 6, 2023. Season seven episodes also air on Showtime on Sundays at 8pm ET/PT.

Season seven stars Paul Giamatti as Chuck Rhoades, Corey Stoll as Mike Prince, Maggie Siff as Wendy Rhoades, David Costabile as Mike “Wags” Wagner, Asia Kate Dillon as Taylor Mason, and Dola Rashad as Kate Sacker. Jeffrey DeMunn plays Chuck Rhoades Sr., Sakina Jaffrey is Daevisha “Dave” Mahar, Kelly AuCoin is “Dollar” Bill Stern, Daniel Breaker is Roger “Scooter” Dunbar, and Toney Goins plays Philip Charyn.

Damian Lewis reprises his role as Bobby Axelrod for the final season.

“Game Theory Optional” Plot: Chuck makes a daring and risky move to demonstrate his unwavering commitment to taking Prince down. Prince gets tipped off about a potential mutiny among his ranks. Wendy is tempted by a new opportunity.

The Season 7 Plot, Courtesy of Showtime:

In season seven, alliances are turned on their heads. Old wounds are weaponized. Loyalties are tested. Betrayal takes on epic proportions. Enemies become wary friends. And Bobby Axelrod returns as the stakes grow from Wall Street to the world.
